ZbaZZ whom it may concern Be it known that '1, JOHN A. Lemons, a citizenof the United States, residing in Ardmore, in the county of Montgomeryand State of Pennsylvania, have invented new and useful Improvements inBox Construction, of which the following is a specification. i 7

My invention relates to the construction of boxes, cartons orreceptacles made of any suitable material, and more particularly to suchas are made of card-board, fiber-board, straw-board, single or doublefaced air-cellboard, paper or the like. a

My invention resides in means for detachably securing to the box propera box wall, such as a top, cover or lid, the construction beingpreferably such that the detachable wall or lid may be suitably packedin small volume with other like lids or covers nested therewith.

My invention resides in the detachable wall, cover or lid of thecharacter hereinafter described, and in the combination of such a lid orcover with the box proper.

For an illustration of some of the forms my invention may take referenceis to be had to the acocmpanying drawings, in which:

Figure 1 is a horizontal sectional View through a box with detachablelid or cover made in accordance with my invention, such section beingtaken, for example, on the line XX of Fig. 3. Fig. 2 showsin perspectivea fragment of the detachable wall or cover in position for assembly withthe box proper, also shown fragmentarily. Fig. 3 shows the partsillustrated in Fig. 2 in assembled position. Fig. 4 is a View inperspective, some parts insection, showing a modification of myinvention, Fig. 5 1s a fragmentary perspective view showing theattaching means' 'illustrated in Fig. 4:. Fig. 6 is a perspective view,some parts in section, of a further modification of my invention. Fig. 7is a fragmentary view in perspective of the box and detachable covermembers of the form shown in Fig. 6 before assembling.

Referring to Figs. 1, 2 and 3, B represents the box proper consistingfor example, of four s des, 1, 2, 3 and 4, it being understood howeverthat the member B may be of any width, length, height, and of anysuitable shape, and as generally provided with a bottom.

At or near two of its corners, inthe case where the detachable wallormember is to operate as a hinged cover or lid, or at four of thecorners, if desired, the box B has may have also the marginal flap 11adapted to embrace the three sides, 3, 1 and 4: of the box 13. Ifdesired the parts 8, 9, l0 and 11 may be made out of a single sheet ofmaterial, or may be of several pieces suitably fastened together.

As will be seen from Figs. 2 and 3, the slots 7 are brought intoalinement with the slots 5 and the parts pushed together until the slots7 straddle or embrace the parts 12 below the sl'ots 5 and the slots 5embrace the parts 6 above the slots 7 of members 8, the flap 9 passingdown outside of the wall 2, while the flaps 8 pass down inside of thebox parallel to the walls 3 and st to the position shown in Fig. 3.

With the parts so assembled the cover may be swung about the edge 13 asa hinge, the fiap 9 pressing the cover firmly and rigidly against thebox, and assisted by the flap 8 turned at right angles to the flap 9 andpreferably lying against the inner wall of the box. 11 may be omitted ifdesired, or may be so disposed as to extend down inside of the boxinstead of around the outside of the same.

I It will be seen that the box B may be flattened for packing, andnumerous covers C may be nested or packed in very small space and laterassembled as above described.

Obviously the marginal flaps- By the construction shown a slot of thebox member straddles the cover member and a slot of the cover memberstraddles part of the box member, and the cover member is provided withflaps inside and outside the box for firmly holding and bracing thecover.

Itwill be understood that the flap 8 is normally in the plane of'theflap 9 and is then bent at right angles thereto as shown, and it willaccordingly be understood that the top edge 14 of the flap 8 is not,attached to the member 10 but is swung in under it, though it is to beunderstood that it may be so attached to the cover member 10 if desired.

In Fig. 4 a side wall 4: of the box B is provided with two slots 15 and16 between which is left the tongue 17 integral with the wall 4. Thedetachable member C has the flap 9 outside of the rear wall 2 of thebox, the same extending around in the flap part 9 and embracing thesides of the box. And a part of this flap 9 which extends into the slot15 is bent back upon itself at 18 to form a loop embracing the tongue 17and terminates in a part 19 extending through the slot 16 and thenbetween the wall 4 and the part 9'. The loop is of a width correspondingsubstantially with the depth of the slots 15 and 16 and has the part 20extending along the inside face of the wall 14 to a distance below theslots 15 and 16, thus forming slots 21 and 22 between members 9 and 20.In this case the cover or lid swings about edge 13 as a hinge. 1

In Figs. 6 and 7, the rear wall 2 of the box B is provided with theslots 15 and 16 leaving between them the tongue 17 integral with thewall 2. Here again the rear flap 9 of the-cover member C lies againstthe out side face of the box wall 2 and has a part bent upon itself at18 to form a loopadapted to receive the tongue 17, and the portionextends outwardly again through the slot 15 and terminatesin the part 19lying between the flap 9 and the box wall 2.

As in Figs. 4 and 5, where the parts'9 and 20 extend below the slots 15and 16 there are formed in efi'ect slots 21 and 22 so that the parts maycome together upon the principle described in connection with Figs. 1 to3, inclusive, it being understood however that theloops of Figs. Land 5and of Figs. 6 and 7 need not have the extensions below the slots 15 and16 in which case there will 7 be no slots 21 and 22.
